I just spent about two hours writing a detailed account of all of the factions in my campaign and the Haarlock legacy but because I didn't write it on Word first I obviously had to lose it all when I backspaced by accident.
In any case- I was just curious as to who was involved in yours game. It seems that, in mine, there's so many- it can get confusing.
Heretics and Hereteks: Logicians, The Amarathine Syndicate [+ Rogue Trader and Crew in Debt], the Beast House, Pilgrims of Hayte, The Cult of Amicus Tole.
Xenos: Eldar & Slaught
Inquisition: Al Subai [Ordo Xenos Puritan], Wrathbone [Tyrantine Cabal Istavanian] & Daemonhunter Ahmazi [Ordo Malleus (in my game an Occularian).
Most of these factions are now on Sinophia Magna- [The Logicians had a renegade Magos there, The Amarathine Syndicate was pulling Legate Sen-Ar Dole's strings before his murder, and now a rogue trader captain has been sent in to finish his job and clean up his estate, The cult of Amicus tole is not only present- but the big guy himself is likely to make an appearance as a key player: having extended his life with the help of sorcery and tech-heresy, it might come as a surprise that he was a member of Haarlock's original crew. The Eldar and the Slaught are both working to keep Haarlock from returning, but both for very different reasons and whereas the first is a Deux-Ex Machine Wild Care that might save the players when they need it [After all, they owe them one favor] the players have already fought the Slaught and stolen their mirror shard. Al Subai and Wrathbone both have agents on the field- Specter Cell 17, whose mission is to hunt down the players, and a Daemon-host whose bindings have been loosened after his original defeat…] Add to that the factions in the book- from the Arbites to the Nobles and the criminal underworld. Not to mention Haarlock and his crew
All in all, my previous write-up was very nice and went into quite of details into the factions and how the have interacted with them since the start of the "Campaign as a whole." Most of these have been met and fought with before- after all, its not unusual that rank 6 acolytes will built up some baggage!
What about you guys? how many villains and factions did your players already accumulate before even starting the legacy? Did you guys dump most of them when it started in favor of the people already there or did you incorporate them into the game [I mostly attempted to do that- linking all the previous factions into a group on Sinophia]?
